The 20-year-old met up with the former One Direction heartthrob just outside the West Hollywood nightclub! One witness told Us Weekly:

"Gigi was leaving The Nice Guy. Gigi went out the front, though. She walked down the street and jumped into the car where Zayn was waiting to pick her up."

Gigi was totally caught on camera in her party outfit (above) cozying up to the ex boy bander in the car! The 22-year-old can be seen looking into her eyes pretty intensely, and even reaching over to touch her arm!
